Problems solved by technology

[0012] In this case, however, the problem with the prior art is that different requirements are set depending on the application situation, so that overall a trade-off has to be made between providing an energy-efficient method with high error sensitivity or being more energy-intensive for improved error-proofing a method of
Therefore, customers cannot tolerate high error sensitivities, moreover, the components to be actuated are usually safety-relevant

Embodiment Construction

[0053] figure 1 The left side of the shows a microcontroller that can be used as a command unit. Furthermore, a plurality of execution units (in this case realized as LED controllers) are configured for bidirectional communication, which is indicated by the reference MLED CTRL. For some application scenarios, existing technologies have the disadvantage that if a controller fails, all other controllers connected in series will also fail due to inhibited communication.

[0054] figure 1 A possible configuration of a system or communication device according to the prior art is shown. So, in this case, the command unit BE connected to the three control units can be seen on the left. Since the three control units are connected in series, the command unit is directly connected to the control unit and indirectly to other control units. The control unit can be a multi-LED controller, in figure 1The middle is represented by MLED CTRL. Uniform reference symbols are used to indicat...

Abstract

The invention relates to a system arrangement for the fault-tolerant and electromagnetically compatible control of a plurality of execution units. The present invention advantageously allows execution units to be controlled such that both a high level of so-called common-mode resistance and a high level of system stability are achieved even in the event of a large number of execution units. The invention also relates to a line driver unit for using in the system arrangement according to the invention and to a method which is used to operate or produce the system arrangement according to the invention. Furthermore, the invention relates to a computer program product containing control commands which implement the method or operate the device.

Description

technical field [0001] The invention relates to a system arrangement for fault-tolerant, electromagnetically acceptable actuation of a plurality of actuators. In this case, the invention advantageously actuates the execution units such that a so-called high level of common-mode resistance and a high level of system stability can be achieved even in the presence of a large number of execution units. Furthermore, the invention relates to a line driver unit for use in the proposed system arrangement, and a method for operating or manufacturing the proposed system arrangement. Furthermore, the invention proposes a computer program product comprising control instructions for performing the above method or operating the device. Background technique [0002] Patent WO 2017 / 162 323 A1 discloses an effective control device and control method, wherein the execution units arranged in sequence are actuated by the command unit. [0003] Patent WO 2018 / 103 880 A1 discloses a compact LED...
